Answer 1

Since I had a similar problem, but the incoming date format was different, here is what you would do should your incoming date format be the following,

Sample input date format,

Tuesday, May 24, 2016
Wednesday, May 25, 2016

You would need to use a different date format,

%W, %b %d, %Y

Here is a link to the mysql documentation and a list of date formats, but briefly,

Date part,

%Y Year, numeric, four digits
%y Year, numeric (two digits)
%c Month, numeric (0..12)
%m Month, numeric (00..12)
%M Month name (January..December)
%b Abbreviated month name (Jan..Dec)
%d Day of the month, numeric (00..31)
%e Day of the month, numeric (0..31)
%D Day of the month with English suffix (0th, 1st, 2nd, 3rd, ?-)

Weekday,

%W Weekday name (Sunday..Saturday)
%a Abbreviated weekday name (Sun..Sat)
%w Day of the week (0=Sunday..6=Saturday)
%j Day of year (001..366)

Time

%T  Time, 24-hour (hh:mm:ss)
%r  Time, 12-hour (hh:mm:ss followed by AM or PM)
%H  Hour (00..23)
%h  Hour (01..12)
%I  Hour (01..12)
%k  Hour (0..23)
%l  Hour (1..12)
%i  Minutes, numeric (00..59)
%S  Seconds (00..59)
%s  Seconds (00..59)
%f  Microseconds (000000..999999)
%p  AM or PM

There are other patterns which are not listed above.

LOAD DATA INFILE '/path/to/temp_test.csv'
IGNORE INTO TABLE temp_test
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\r\n' #use '\n' for linux
  IGNORE 1 LINES
(@var_col1, col2)
SET col1 = STR_TO_DATE(@var_col1,'%d-%b-%y %H:%i:%s');
